A few days ago, I tried to install the Nvidia GTX 750 Ti graphics card [I previously used the 550 Ti]. While it did "work" [Computer booted, could run games, etc], there were severe issues.


Namely, the graphics card would lag my PC to hell when attempting to run any game that had decent graphics [Even games like Borderlands 2 and World at war that I could easily run previously]

After attempting many solutions [including cleaning drivers, registries, messing with settings, and more], I eventually caved in and put my old GPU back in [which still works]. I can confirm that the problem was not overheating or power supply.




The gpu was a Nvidia GTX 750 Ti, specifically the "FTW w/ ACX" version. FTW means that it is overclocked, while ACX is just some fancy cooling system. I was thinking that perhaps my computer wasn't configured to support the extra overclocked capabilities of the GPU, but I don't know how I would do that [assuming that is the problem].



So my question is, do any of you know why this might have happened, and do you guys have any idea about what I should do? I was thinking of returning the GPU and getting the standard [non FTW] edition.

[By the way, the main specs are
850W Power Supply
Nvidia GTX 750 Ti
Intel i7-3770K 3.5 GHz
16 GB RAM
Really good cooling system

As I said, I could and still can run games with my inferior graphics card much better than my current one, so I seriously doubt that the other hardware is the issue]

Did you plug in the power to the additional 6-pin connector on the card?

Might need to update the bios on your motherboard.

There was not a slot for an additional connector. Would an issue like this be caused by the motherboard's BIOS? I would want to be sure, as BIOS updates are a pretty big deal.

There is indeed a 6-pin connector on that card, like maxalge suggests; plugging a PCIe power cable in here will likely help with your issues. It's on the top of the card (bottom of the image), between the two sets of fins:
